TPS61196EVM-600: 200mA @ 60V Max, 10 ~ 30V in

Summary

This user’s guide contains background information for the TPS61196 as well as setup and operation instructions for the TPS61196EVM-600 evaluation module (EVM). Also included are test results, printed circuit board (PCB) layouts, schematics, and the bill of materials (BOM) for the EVM.

TI's TPS61196EVM-600 evaluation module contains the TPS61196 integrated circuit (IC), a six-channel, 400-mA WLED driver. The TPS61196 provides a highly-integrated solution for LCD TV backlight with an independent PWM dimming function for each channel. This EVM helps designers evaluate the operation and performance of the TPS61196. The EVM contains one DC/DC converter as shown in Table 1.

The EVM is designed to operate from an input voltage source ranging from 10 V–30 V, and provides a continuous 200-mA output current for each string. The OVP voltage is set to 60 V but can be adjusted for the specific application.

Table 2 provides a summary of the TPS61196EVM-600 performance specifications. All specifications are given for an ambient temperature of 25°C.
